Struct kernel::list::ListArcField

source · 
pub struct ListArcField<T, const ID: u64 = 0> { /* private fields */ }
Expand description

A field owned by a specific ListArc.

Implementations§

source§

impl<T, const ID: u64> ListArcField<T, ID>

source

pub fn new(value: T) -> Self

Creates a new ListArcField.

source

pub fn get_mut(&mut self) -> &mut T

Access the value when we have exclusive access to the ListArcField.

This allows access to the field using an UniqueArc instead of a ListArc.

source

pub unsafe fn assert_ref(&self) -> &T

Unsafely assert that you have shared access to the ListArc for this field.

§Safety

The caller must have shared access to the ListArc<ID> containing the struct with this field for the duration of the returned reference.

source

pub unsafe fn assert_mut(&self) -> &mut T

Unsafely assert that you have mutable access to the ListArc for this field.

§Safety

The caller must have mutable access to the ListArc<ID> containing the struct with this field for the duration of the returned reference.
